According to Apple's patent applications in the US and Europe, they have made new progress in fingerprint recognition under OLED screens. The OLED screen adheres to the touch screen and OLED dot matrix to the glass or plastic panel, eliminating the need for a backlight, automatically emitting light and being very thin, but it is also officially so that any circuit or touch sensor will be integrated to make the OLED screen It became very thick.Apple's patent is about the design of silicon-based OLED screens and touch sensors, which can be used in mobile electronic devices such as mobile phones and tablets. Silicon-based OLED (OLED Microdisplay) arrays can have ultra-high pixels per unit area, sub-pixels can be arranged side-by-side with touch sensors, making the entire screen thinner and brighter, and allowing OLED screen to be used without sacrificing touch sensitivity. Larger viewing angles, higher brightness and contrast, and more vibrant colors. Due to the higher pixels per unit area, this structure can also integrate more components, including electrostatic discharge devices, near-field imaging systems, near-infrared emitters, near-infrared receivers, and the like. These components help the entire device reduce energy consumption, improve touch sensitivity, and improve fingerprint recognition.FIG. 9A cross-sectional view shows a panel with a silicon-based OLED screen (OLED Microdisplay) combined with a touch sensor with a fingerprint recognition function. When a finger touches or slides the screen, the transistor can use a near-field imaging system to detect a fingerprint image through the "peak" of the fingerprint. "The valley" reflects back different light, collects fingerprint information, and generates a black and white image of the fingerprint.Another patent released together is the design of a silicon-based OLED and touch sensor panel combined with a fiber amplifier. Parallelizing the Fiber Channel into a cone is connected to the real panel to magnify the image, and the different shapes of the Fiber Channel determine whether the screen is flat or curved.
